  2. 2. Collabor8now Ltd What is “Big Data”? Big Data is data whose scale, diversity and complexity require new architecture, techniques, algorithms, and analytics to manage it and extract value and hidden knowledge from it…
  3. 3. Collabor8now Ltd Big Data – Big Challenges • Structured e.g. databases • Semi-structured e.g. email, e-forms, HTML, XML • Unstructured e.g. document collections (text), social interactions (text, images, video, sound) • Machine generated e.g. weblogs, sensor data, etc. Big Data can be a combination of different data formats: There is massive growth in unstructured data…but just wait for the IoT!
  4. 4. Collabor8now Ltd Big Data Challenges Image Source: IBM It’s not just how fast data is produced or changed, but the speed at which it must be received, understood and processed.
  5. 5. Collabor8now Ltd The credibility gap Collabor8now Ltd Time DataVolume Data available to an organisation Data an organisation can process
  6. 6. Collabor8now Ltd Data-driven decisions Source: PwC Global Data & Analytics Survey 2016 8% 53% 39% Highly data driven Rarely data driven Somewhat data driven Decision making is best described as 27% 28% 29% 13% Predictive: What could happen? Use of analytics is mostly Prescriptive: What should happen now? Descriptive: What happened? Diagnostic: Why did it happen?
  7. 7. Collabor8now Ltd What do decision-makers need? Strategic decisions are still often based on instinct. But more businesses are beginning to look at sophisticated machine learning algorithms to support decision making. Our next decision will likely be based on: Machine Algorithms Human Judgement 59% 41% Source: PwC Global Data & Analytics Survey 2016 A mix of mind and machine

  10. 10. Collabor8now Ltd Analytical Techniques Cluster analysis The task of grouping a set of objects in such a way that objects in the same group (cluster) are more similar, in some sense or another, to each other than to those in other groups clusters). Comparative Analysis. A step-by-step procedure of comparisons and calculations to detect patterns within very large data sets Descriptive tree analytics A decision support tool that uses a tree- like graph of decisions and their possible consequences including chance event outcomes, resource costs and utility Factor analysis Used to analyse large numbers of dependent variables to detect certain aspects of the independent variables (factors) affecting those dependent variables. Machine learning A type of artificial intelligence which provides computers with the ability to learn without being explicitly programmed. Multivariate analysis The observation and analysis of more than one statistical outcome variable at a time.. Regression analysis A statistical process for estimating relationships between a dependent variable and one or more independent variables. Segmentation analysis Divides a broad category into subsets that have, or are perceived to have, common features, needs, interests or priorities. Sentiment analysis The process of identifying and categorising opinions expressed in a piece of text to determine whether the writer’s attitude towards a topic or issue is positive, negative or neutral. Simulation The imitation of the operation of a real world process or system over time. It requires a model that represents the key characteristics or behaviours of the selected physical or abstract system or process. Time Series analysis Comprises methods for analysing time series data to extract meaningful statistics and other characteristics of the data.
  11. 11. Collabor8now Ltd The art and science of decision making Unlock existing insights. Data do not have to be “big” to be useful.Analysing databases previously mothballed or kept in silos can lead to fresh insights. 1 Beware of inherent bias. Important decisions have already taken place before data analysis. Understand the provenance and quality of the data. 2 Invest in talent. Can you give existing employees a foundation in data analysis before recruiting new data scientists? 3 Accountability. Be clear about who has decision making rights. Opening up access to data and analysis can allow decisions to be challenged. 4
